收藏: Diamond Concave Wheels
Diamond concave grinding wheels feature an inward-curved diamond rim that matches and grinds convex stone surfaces, cabochon backs, and curved lapidary profiles with full surface contact. Where flat wheels leave high spots on curved surfaces, a concave wheel conforms to the convex profile — delivering even, consistent material removal across the entire curved surface for precise, controlled shaping.
Applications
- Grinding convex cabochon backs to a consistent curvature
- Shaping curved stone surfaces and rounded lapidary profiles
- Finishing convex decorative stone elements
- Grinding the convex face of carved stone pieces
- Matched-profile grinding for stone setting preparation

Frequently Asked Questions
-
Q: What is a concave diamond wheel used for?
A: A concave diamond wheel has an inward-curved rim that matches convex stone surfaces. It is used for grinding the convex backs of cabochons, shaping rounded stone profiles, and any application where a flat wheel would only contact the highest point of a curved surface rather than grinding evenly across the full curve. -
Q: Should diamond concave wheels be used wet or dry?
A: Always use wet. Run water over the wheel continuously during grinding to cool the diamond surface, prevent heat damage, and suppress stone dust.
